Chris Evans as Steve Rogers in 2011’s Captain America: The First Avenger

Speaking to Varietyabout the superhero movie boom, Marvel Studios boss Kevin Feige issued a small dose of insight into where Captain America 2 fits into the grand pattern.

“If it is a fad,” Feige said of comic-book movies, “it’s one that lasts 30 to 40 years, as the Western did, because each one is so different. There’s an opportunity to graft almost sub-genres onto them.

“Our first Captain America film was a World War II picture, and the next is a political thriller. They all have their own textures and patinas, and that’s what is exciting about it.”
